Hi,
I'm trying to use pvmove to move a vg from one pv to another.
This is with whatever is the latest version of the kernel and lvm
tools on FC6,
[root@zaphod /]# lvm version
LVM version: 2.02.06 (2006-05-12)
Library version: 1.02.07 (2006-05-11)
Driver version: 4.7.0
[root@zaphod /]# uname -a
Linux zaphod 2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:34:46 EST 2006
x86_64 x86_64 x86_64 GNU/Linux
The "rbig" volume group is on both /dev/13 (full) and /dev/md8 (same
size, empty) and a few others.
[root@zaphod /]# pvmove -v /dev/md13 /dev/md8

pvmove --abort sometimes locks up the lvm subsystem (or the device-
mapper, I've no idea how it works) requiring a reboot. Sometimes it
seems to work and lets me try the pvmove again.
Any ideas?
